Was Posidonius really the Stoic who abandoned Chrysippus’ psychology in favor of Plato? This book offers a new reconstruction of Posidonius’ theory of the passions and reassesses his place within the Stoic tradition. Drawing on a close textual and philosophical analysis of Galen’s De Placitis Hippocratis et Platonis and the surviving evidence, the study argues that Posidonius did not abandon the rational and monistic foundations of Stoic psychology. Rather, he sought to refine the Chrysippean account of the passions by developing a new explanation of their causes and of the so-called passionate movements. By distinguishing Posidonius’ own doctrines from Galen’s interpretation, the book reconstructs his psychology and reassesses his contribution to the development of Stoic thought, presenting him as an innovative Stoic thinker whose revisions remain firmly rooted in the monistic framework of the Stoic school and anticipate important themes of Roman Stoicism.
